Ryan's past self and his fellow disciple are demon exterminators going to a conference of demon exterminators who will discuss how to get rid of the evil black dragon that caused demons to appear again and cause trouble in the mortal world, not knowing that the new guy with them (the white haired Xuan Yue who is AoAo's past self) is actually that black dragon himself, and he's not really evil like all the humans think, he's just been cursed to house demonic energy inside himself against his will, and has no control over the demons that keep showing up because they're attracted to the energy inside of him.
Omg thank you so much! I love you
I get this is in the past but what are they doing right now? Where are they and why are they there? Did their leader tell them to go there? Why?
